Before You Go
While your stylist will wash your hair prior to the treatment, it is best to show up for your keratin straightening without product in your hair. Take a book or make sure your phone is charged up, as it can be a lengthy process, especially if you have long hair.
If you dye or otherwise chemically treat your hair, wait two weeks after your last treatment before getting keratin straightening.
After care for Keratin Hair Straightening: After the keratin treatment, you will not be able to wash, bend or tie back your hair for up to four days. If it rains, you may have to gently tuck your hair underneath a shower cap in order to shield tresses from moisture. Consider sleeping on your back on a satin pillowcase to avoid mussing hair during the night. Make sure to have a flatiron handy. If you mess up your hair, you will need to flatiron it back into shape.
After you wash out the treatment, only wash your hair with sulfate-free shampoo and conditioner. Avoid salt water, as this can strip the keratin coating from the hair.
What To Expect
You hair will first be washed before a keratin straightening treatment. Then the keratin treatment is applied to each strand of hair. The hair is blown dry, and then straightened with a flatiron. The entire process takes 90 minutes to three hours, depending on the length and thickness of your hair and the skill of your stylist.
You may notice stinging of the eyes or a chemical odor as the keratin treatment is heated by the flatiron. Many salons will provide you with a face mask. If not, ask.
After keratin straightening, hair is typically much straighter and less frizzy. Results last for up to three months.
Keratin straightening treatment can be used on all types of hair, including black hair, dyed hair and damaged hair.
